How to set var1 from first commandline argument?

Answer 1

The correct assignment is simply the following, with no spaces on either side of the equal sign:

var1=$1

The command set var1 = $1 actually does the following:

1. Sets the value of $1 to "var1"
2. Sets the value of $2 to "="
3. Sets the value of $3 to the original first parameter $1.
